FAQs

Installation begins with confirming the 19-300 Vdc / 40-250 Vac power supply range and 50/60 Hz compatibility. Mount the unit semi-flush, attach the removable terminals, and connect the 8 digital inputs and 9 outputs to the protected transformer circuit as per the wiring diagram. Ensure RS-485 Modbus RTU and Ethernet TCP/IP are configured in the control system for remote monitoring. Use the Trip Coil Monitor and URTD/IRIG-B interfaces as required for your protection scheme. Finally, verify communication with the SCADA/EMS and perform a functional test to confirm fault detection and isolation operations.
Important electrical specs include a dual power range of 19-300 Vdc or 40-250 Vac, 50/60 Hz operation, and phase current options of 5A and 1A. The device provides 8 digital inputs and 9 digital outputs, 2 current-sensing inputs, and supports Modbus/RTU over RS-485 as well as Modbus TCP over Ethernet. These specifications enable flexible integration with mixed-voltage transformer protection schemes and plant-wide control systems.
Yes, the ETR-5000-2A0IA0 is designed for transformer protection in industrial environments, offering8 inputs, 9 outputs, and multiple communication options (RS-485 and Ethernet) to integrate with existing control architectures.
